ECM Chips for 72LB Injectors

[CPAKCP]

Thought I post this thread to put in a plug for Brutal Six Racing aka Neal Steward. I had been having a fuel issue with my combo. and wanted to step up to 72(s) - was running 55 (s). Steve Wood told me about Neal, and Neal's chips have worked great in my car. His street chip for the 72(s) idles great - great street manners. His race chip - put my car in the tens just this past weekend.

Thanks again Neal you are the chip man

Glad it worked out for you...Neal does not get enuf credit for his talents.

I Was hoping this answer would come up.

Awsome! a person who can feel comfortable about making 72lbs chips for the street? any contact numbers for this 72 chip guru?

great times! whats the rest of the combo?

Jim,

Thanks for the good word. Keep up the good work!! I expect many more 10 second passes in the future.

Hey James your car ran great!! Mike's car also looked very good! I will be switching to 72 lb inj and double pumpers in the very near future. Gilbert

72 inj with fuel management by Brutal 6, Prec. 9.5 N/L converter - 3200 stall, trans brake in not used yet

All the other usual stuff. The car has excellent street manners - the cam never stops pulling and I still am amazed how these 72 inj. act on the street. Couldn't be happier. Next step is a roll cage.

sounds like a plan! i'm in the same boat. good luck!

Cutt,

Just E-mail Neal through the message board here. On the bottom of Neal's post (750hp V-6) just click on private e-mail or e-mail. I think Neal can take care of you!!!

Good Luck

Matt, what results have you had with your combo.?? Our packages are pretty close!!

 

[matt87]

unfortunatly i havnt made it to the track at all this summer. hopefully in the spring after a cage goes in and i shed a few pounds to compensate. i ahve beat up on a few 11 sec stanges at the local street scenes. i have great air quality at sea level in RI. i'm very happy with this combo, the only difference i see in our setups is fuel managment and cam choice.

I'd like to chime in here as well. Mr. Steward just got done assembling a Stage 2 motor for my car.......very meticulous, very knowledgeable with these engines. I've been running his chips for the past 5-6 years and we've always got them right on the money....ie. (no parts breakage). Currently I'm running MSD 75lb injectors with the stock ECM and the car runs extremely well. He continues to find stuff to improve on with his chips.

I would like to know why you went with bigger injectors . I mean no dissrespect but you could go alot faster than your going with 55. I ran 10.83@125 at 3850 lbs. with 50 lbers with 38 lbs of fuel at the rail with my max-effort. I ran a buddys car at bowling green we ran 10.40s@130+ with 55lbers. So why do you need 72 lb injector ? The reason i ask is that most cars run better with a smaller injector with a chip and a stock ecm(not max-effort) . Laz

Laz, I like the bigger injectors for safety reasons. Try to minimize potential damage to my motor and HG. I don't want to go lean!!! Why run a 100% duty cycle on an injector when you don't have to!! Also, by running a lower static FP, your pump(s) or injectors don't have to work as hard.

You are doing a great job with your Max-effort. I have a good friend(uses Max-Effor) that has run 10.60(s) with 50(s) but his static FP is a lot more then 38, and he has modified his fuel rail.

Keep up the good work

Just depends on what you actually call tuning.
If you consider running an injector static, and goofing around with timing and boost as tuning, then your OK to do that.

If you want to run at less then static and develope an actual fuel map then that takes larger injectors and more work.

Build an ecm bench and listen to an injector misfire, as it tries to go static and you can appreaciate how wrong static really is.

OK the reason i asked is because you said a street chip right . I run 72 lbers now and my car will knock at anythng more than 13 lbs of boost on pump gas. I can`t see any buick needing that much injector at your level. I tryed running a street chip with 65 pecent duty cycle and it would flood my 231 in third gear. You might find out that you car will run alot faster with smaller injectors . I never broke anything on my car and know a few guys that run 10.90s on 009 injectors . The 55 lbers you had support 660 hp. at 43 psi the 72 lbers support 864 hp. i can`t see why you would not run 55s. To Bruce 55 lbers running hi tens is nowhere near static but if you can work a fuel map with a stock ecm and a chip and run lean enough not to wash down the cylinders with 72s thats great.

Laz,

I agree with part of what you're saying but I honestly believe that having large enough injectors to support whatever H.P. you make at the track make the most sense.

As you stated 55 lb injectors can support 660 H.P. at 100% D.C. and can nose you into the 10 second range. To run 10's in a 3700 lb car takes around 600 H.P. so you will be at 90% D.C. +.

There is no reason that the P/E fuel flow on the street chip can't be tailored to give you the same O2 mv or EGT as the smaller injector. If the calibration is correct start up, drivability, and even mileage should be similar. Who's chips are you using?

BTW, Bruce is a genius with this stuff so I wouldn't argue with him myself. Just my opinion.

Laz, I don't know how Neal has done it, but we have run 17 LBS of boost on my 72(s), (street chip-93 octane) not only did the car not knock it flat out hauled ass!!
